What's wrong with
% find . -name '*.[ch]'|xargs perl -pi.bak -e 's/^( +)#/#$1/'
in the base of the exim source tree, which changes
#if ...
#include ...
to
#if ...
# include ...
Not only does it preserve the indentation while keeping older cpps
happy, it also helps other tools which rely on pre-processor
directives starting with # in column 1, such as the syntax colouring
in Emacs cc-mode.

-std1 for strict ANSI compliance; -std for ANSI compliance with some
allowances, -std0 for K&R.
