Probably easier: the "quotearg" bit of the shared GNU library

https://gitweb.git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/quotearg.h;hb=HEAD

https://gitweb.git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/quotearg.c;hb=HEAD

It's used by `ls`, `cksum`, and others that have to display filenames
to the terminal. It's *exactly* Michiel's use-case. The header file
contains a description of the various styles, and the most relevant
function is `quotearg_buffer_restyled`
