Subject: cache.c: cache ls_cache output properly
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/f32a2da636ffa6eaa6b8d0d3f35a673fa12e404a?hp=f32a2da636ffa6eaa6b8d0d3f35a673fa12e404a

cache.c: cache ls_cache output properly

By using the standard library's printf, cache_ls does not redirect its
output to the cache when we change the process' stdout file descriptor
to point to the cache file.  Fix this by using "htmlf" in the same way
that we do for writing HTTP headers.
