diagnostics: support --color=html
Based on a message from Bruno Haible.
https://git.savannah.gnu.org/gitweb/?p=gettext.git;a=commitdiff;h=fe18e92743b7226791a5f28d7c786941a1bf8cc9
This does not generate proper HTML: special characters are not escaped
for instance. This is a hidden feature meant for Bison developers,
not end users.
* src/complain.c (complain_init_color): Support --color=html.
