Subject: Use "doc" man page format if mandoc present.
X-Git-Tag: V_8_1_P1~245
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=285546b;p=thirdparty%2Fopenssh-portable.git

Use "doc" man page format if mandoc present.

Previously configure would not select the "doc" man page format if
mandoc was present but nroff was not.  This checks for mandoc first
and removes a now-superflous AC_PATH_PROG.  Based on a patch from
vehk at vehk.de and feedback from schwarze at usta.de.
