Quick fix for ncurses buffering issue with inotify polling.
Ncurses does its own buffering for some character sequences, notable
Esc-prefixed input. Add a non-blocking check for getch() before
performing the mutt_monitor_poll() call.
This is a quick fix, which I'll clean up more later.

Add GnuPG status fd checks for inline pgp.
The difficulty is that "BEGIN PGP MESSAGE" could be a signed and
armored part, so we can't fail hard if it isn't encrypted.
Change pgp_check_decryption_okay() to return more status codes, with
>=0 indicating an actual decryption; -2 and -1 indicating plaintext
found; and -3 indicating an actual DECRYPTION_FAILED status code seen.
Fail hard on -3, but change the message for -2 and -1 to indicate the
message was not encrypted.

Add $pgp_check_gpg_decrypt_status_fd.
If set (the default) mutt performs more thorough checking of the

Ticket #39 revealed that GnuPG (currently) does not protect against
messages that have been manipulated to contain an empty encryption
packet followed by a plaintext packet.
A huge thanks to Marcus Brinkmann for researching this issue, taking
the time to report it to us (and the GnuPG team), and taking even more
time to clarify exactly what needed to be checked for.

Add new timeout functions to work with inotify monitors.
The ncurses timeout() function doesn't affect the new poll inside
mutt_monitor_poll(). This meant that $imap_keepalive and $timeout
were not being respected when the monitor was used.
Create mutt_getch_timeout(), which delegates to timeout() and sets a
timeout value mutt_monitor_poll() uses too.

Fix mutt_strncmp size comparison for 'uncolor header'.
Thanks to Fabian Groffen for pointing out the discrepancy.
mutt_extract_token() null-terminates the token,, so actually there is
no need to use "strncmp" for the comparison in this case.
However, since the token is being checked against Fields there is no
potential harm of a prefix match, so we should fix the number to be
consistent with the other token comparisons.

Update pattern documentation.

Change =b, =B, =h table rows to document just the IMAP behavior. The

Add $browser_abbreviate_mailboxes.
This allows '=' and '~' mailboxes shortcuts to be turned off in the
browser mailbox list.
The default $sort_browser value of "alpha" uses strcoll(3), which
ignores some punctuation. When using multiple accounts with
dynamically changing values of $folder, this can lead to an
unintuitive sorting order. (See issue #22 for an example.)
This problem came about because of commit 8328ce68, which enabled
mutt_pretty_mailbox() calls for IMAP and POP mailboxes too. The
commit had a valid point about consistency and too-wide mailbox
listings, so I don't really want to revert it.
This option provides an alternative to completely enable/disable the
shortcuts for those who run into an issue.

Improve gss debug printing of status_string.
Commit f52ee2f7 ensured the debug strings were properly '\0'

Rename _regex.h to _mutt_regex.h to avoid name collision on Macs.
On Macs, <regex.h> includes <_regex.h>. Because Mutt defines '-I .'
during compilation, our bundled version of _regex.h was being used
instead of the system one.
I have no idea how it managed to work before, but starting in Xcode
9.3, the differences in struct size and fields started to produce a
crash and other strange behavior.
The real issue is our use of '-I .' during compilation, which allows
our local headers to override system ones. An easier fix for now is
to rename the header.
Many thanks to Charles Diza, Christian Ebert, and Fabian Groffen for
their help trying things out and helping to debug the problem.
Also, a huge thanks to Steve Karmeinsky for allowing me to ssh in to
his Mac so I could track down the underlying issue.
