    Erik Heckers fixed bug #493 · f037300c
    Sam Lantinga authored
    Searching the installed man pages for SDL functions fails, e.g.
      man -k SDL_ |grep Video
    After investigating this I found that "makewhatis", the tool that generates
    the "whatis" database, reads the SDL_* man pages, but doesn't produce
    entries in the "whatis" database for the SDL_* man pages.
    After some more debugging I found the reason is a missing space.
    After editing SDL_Init.3(.gz) and replacing
       SDL_Init\- Initializes SDL
    with
       SDL_Init \- Initializes SDL
    everything works fine.
    After running "makewhatis" I can successfully do a
       man -k SDL_
    and SDL_Init is listed in the output.
