in 1a0c81fb61 I've added a range check too strict for max_repos_display, as zero is allowed and means "show all the repositories".

saves a bit fiddling around with ternary operators. sockets_run() will reset the chroot to the default since it calls again config_init(), but at that stage it's not important anymore. ok stsp@

Supporting both "no" and "on" as valid syntax with an opposite meaning could easily result in accidental misconfiguration. Suggested by stsp, tracey agrees. Patch by Josiah Frentsos, thanks!

While they're the same value, it's more correct to use AF_UNSPEC in this case. While here, change SOCK_DGRAM to SOCK_STREAM since it's what we'll be using. ok stsp@

host_dns() (now just host()) uses getaddrinfo() which knows already how to handle IPv4/IPv6 addresses. Saves a good amount of duplication. ok stsp@

simplify gotweb_process_request more, handling all the pages inside the big switch. There's only one entrypoint for rendering the templates gotweb_render_page() that takes the page' content as argument. The only real difference is that gotweb_render_index() now skips directory entries which fails to handle. ok tracey@

and drop unix_socket and unix_socket_path in server context. ok stsp@

allows to hide repositories if they have the magic git-daemon-export-ok file ok op@ tracey@ stsp@

macros are already supported by parse.y but can only be defined with the -D flag. This adds the ``usual'' syntax for macros: varname = string. While here, fix the markup of the -D flag in the SYNOPSIS and sync the global `grammar' yacc rule with other parse.y grammars in base: - add the /* empty */ comment - increment file->errors on errors ok stsp@, "sure, go for it" tracey@

Avoid crashing by corrupting the pointer instead of writing to it and fix how sym is generated: it shouldn't include the '=' sign. ok / improvement tb@
