annotate arogue5/sticks.c @ 233:0990adf580ee

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Declare some function arguments as const. Some functions, mostly in fight.c, declared variables as pointers to const char but passed them to functions that took pointers to ordinary char. The strings did not actually get modified, so adding 'const' to the function definitions removed the warnings.
