Subject:    [PATCHv2 3/5] ui-shared: make a char* parameter const
From:       Jeff Smith <whydoubt () gmail ! com>

All cgit_xxx_link functions take const char* for the 'name' parameter,
except for cgit_commit_link, which takes a char* and subsequently
modifies the contents.  Avoiding the content changes, and making it
const char* will avoid the need to make copies of const char* strings
being passed to cgit_commit_link.
