Subject: html.c: add various strbuf and varadic helpers
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/fd00d2f9d6088223f57006949dc6ce7c36316a79?ds=sidebyside;hp=fd00d2f9d6088223f57006949dc6ce7c36316a79

html.c: add various strbuf and varadic helpers

This adds the fmtalloc helper, html_txtf, html_vtxtf, and html_attrf.

These takes a printf style format string like htmlf but escapes the
resulting string.  The html_vtxtf variant takes a va_list whereas
html_txtf is variadic.
