[Lemon-devel] TABs vs. SPACEs

[Balazs Dezso]

Hi, 

I support this idea, but I would like to recommend a few more, the trailing 
spaces should be removed from each line (maybe if the line contains not 
whitespace characters), and the long lines (excluded some special cases) 
should be wrapped.

I also would like to recommend some automatic checking, which coule be done 
with the usage of hg commit hooks. A checker script could be included into the 
repo, which could check the changeset before each local commit.

Best, Balazs
