indent.vim should not overload existing indent function

[Manuel Pégourié-Gonnard]

Hi,

indent.vim correctly sets b:did_indent, but doesn't check if it is already set. As a result, if the user already has a custom indent.tex.vim, its effects are lost.

Would you please consider adding

if exists("b:did_indent") | finish | endif

at the beginning of the file?

Thanks,
Manuel.
