Subject: Cleanse help texts of some common TeX escape codes
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=6e119123be4cf0ac4b922318e8855ee9c71743cd;p=xboard.git

Cleanse help texts of some common TeX escape codes

The TeX escapes \s-1, \s0 around all-capital words, \*(L, \*(R for
distinguishing left/right quoting, a mysterious \& and a \ in general
(e.g. for \- as forced hyphen) occur quite often in the man-page text.
They now no longer clutter the help popups.
