Tcl's msgcat library and corresponding mc procedure can locate a translated string for any user message, provided that it is first given a directory where the *.msg files are located containing the translations. During installation we will place the translations in lib/msgs/, so we need to inform msgcat of this location once we determine it during startup. Our source code tree however will store all of the translations within the po/ directory, so we need to special case this variant. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
