[Po4a-devel]man module: .IP's designator should be translatable

Hello, In the useradd.8 manpage, there is the following groff lines: .IP "\fB-c \fIcomment\fR" The new user's password file comment field. .IP [...] At this time, the designator is only translatable if the indentation is set (second argument to the .IP macro). With the current po4a, the argument to the -c option can't be translated. The attached patch should correct this. I'm not used to perl, please corect my patch if needed. Regards, -- Nekral
