Johannes Altmanninger 6f28178b91 rc filetype: add trim-indent hooks to all languages that have indent hooks
An indent hook automatically adds whitespace, so it seems prudent to
add the hook to remove unwanted whitespace again. This is what we do
in most languages already.

# Indentation
# -----------
# Coq's syntax is based heavily on keywords and program structure,
# not based on explicit, unique delimiters, like braces in C-family.
# So it is difficult to properly indent using only regex...
# Hence here only a simple mechanism of copying indent is done.
