Subject: The builtin pager tries to wrap a line for ever
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=28eddeb07ca98167b277e9d8d651f018a9f0f934;p=neomutt

The builtin pager tries to wrap a line for ever
if:
0) the line contains a space or a tab character
 followed by a very long word, and
1) M_PAGER_NSKIP flag is passed to it, and
2) $smart_wrap is set. (default)
