Subject: exigrep: do case sensitive option processing again. Closes 2392
X-Git-Url: https://git.exim.org/users/jgh/exim.git/commitdiff_plain/82a996b1cc5a4299674260962778fc2ad1f2f75e

exigrep: do case sensitive option processing again. Closes 2392

-M (--related) was hidden by -m (--man), because of case insensitive
option matching. (4.90 … 4.92 did case insensitive option processing)

Thanks to Andreas Metzler for reporting this issue.
