g.manual is a script. Currently, there is no mechanism for translating
messages within shell scripts (the "help" output is generated by
g.parser, which translates labels, descriptions, etc). 7.0 uses Python
for scripts, which can use Python's gettext module for translation.

In theory, it would be possible to extend g.message to support
translation. One complication is that any substitutions would have to
be perfomed by g.message after the template string has been
translated.

E.g. g.manual does:

    g.message -e "No HTML manual page entry for <$1>."

where $1 is the name of the manual page. The shell substitutes the
value into the string passed to g.message, which only sees the final
string.

If g.message just translated the message= argument, you would need a
separate translation for each manual page. So it would need to accept
a template and a list of substitutions, e.g.:

    g.message -t -e "No HTML manual page entry for <%s>." subs="$1"

The template string would be translated, then the parameters
substituted, and the resulting string passed to G_message(),
G_fatal_error(), etc
