Various updates, mainly related to uppercasing SH titles:
- added a "Language: " metadata line to the top comment area of
output man pages, to indicate the language the page is in
- added a "toupper" macro of doing locale-aware uppercasing of
SH titles and cross-references to SH titles; the mechanism
relies on the uppercase.alpha and lowercase.alpha DocBook
gentext keys to do locale-aware uppercasing based on the
language the page is written in
- added a "string.shuffle" template, which provides a library
function for "shuffling" two strings together into a single
string; it takes the first character for the first string, the
first character from second string, etc. The only current use
for it is to generate the argument for the groff tr request
that does string uppercasing.
- added make.tr.uppercase.arg and make.tr.normalcase.arg named
templates for use in generating groff code for uppercasing and
"normal"-casing SH titles
- made the BB/BE "background drawing" macros have effect only in
non-TTY output
- output a few comments in the top part of source
