Re: Fwd: cannot search for -a in man inside mintty under cygwin-1.7

it's actually -

any idea?
This was discussed here before but I'm not sure whether a solution was already outlined.
The problem appeared on Linux too, some years ago, but has been fixed meanwhile.
Differences are:
man calls nroff -mandoc on cygwin, nroff -mandocdb on Linux. The latter macro package of groff includes the following which is prepended to the manual page before feeding it to nroff for formatting:
.if '\*[.T]'utf8' \{\
. char \- \N'45'
. char - \N'45'
. char ' \N'39'
. char ` \N'96'
.\}


Checking the program chain of 'man' with procps, some other macros are added already (simply using 'echo'), that's where it could also be added without a complete new macro package (i.e. without changing groff). However, the auxiliary roff codes are apparently hard-coded in man.exe so that'll have to be changed.
