[Bug 2054670] [NEW] troff: warning: cannot select font 'C' when viewing man page

[Dominik Viererbe]

Public bug reported:

When viewing any man page the following warning is displayed:
troff: warning: cannot select font 'C'

Run any of the following commands to see the warnings yourself:
$ man funzip > /dev/null
$ man unzip > /dev/null
$ man unzipsfx > /dev/null
$ man zipgrep > /dev/null
$ man zipinfo > /dev/null

This is a new warning. Other projects replaced the \fC directives with
nothing, as it is currently a no-op.

Context: \fC sets the font to a monospace font. The terminal can not
change the font to any other font than a monospace font. Therefore
removing the \C directives should result in no visual change.

I already prepare a patch.
