Subject: Improve interior dashes in long options.
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=353506bc51a87e8df2ea12289786689ff9d44d14;p=thirdparty%2Frsync.git

Improve interior dashes in long options.

Improve the backslash-adding code in md-convert to affect dashes in the
interior of long options.  Perhaps fixes #686.
