  Added:       webapp/support formatfile.c
  Log:
  Added a simple and stupid proggie that:
  - Reads your source file
  - Trims all the white-space on the right of each line
  - Converts tabs-to-spaces (1 tab = 4 spaces) on the left of each line
  - Tells you if one of the lines is longer than 80 columns
  This is what I use for checking/cleaning sources before commits (and
  sometimes after, when I forget!) and it's kinda useful.
  
  DO NOT USE ON MAKEFILES: Makefiles REQUIRE tab characters.
