spaces before tabs

Thus spake style(9):
 >     Do not add whitespace at the end of a line, and only use tabs 
followed by
 >     spaces to form the indentation.  Do not use more spaces than a tab will
 >     produce and do not use spaces in front of tabs.

   There are somewhere around 6500 lines in 1000 files which violate this final
rule.  Should I clean these up, or is it not worth bloating the repository for
such cosmetic fixes?
