Feature request: add option to add comment mark always at first column

[cristobaltapia]

Hi, I have been using this plugin for a long time now and it is very useful. So thanks for sharing it!

Recently I have been programming in fortran77, where the comments are of the form

      var = 1
C     Some comment
      Var2 = 2
C     Some comment
C     Some comment

Since fortran always has these 6 spaces at the beginning, the C mark would be placed always at that position, but that is incorrect. It would be useful in this case to have an option to force the insertion of C always at the first column.

Would you consider such an option?
