[issue3148] export is affected by diff settings

[Sam Steingold]

New submission from Sam Steingold <sds at gnu.org>:

adding 

[diff]
showfunc = true
ignorews = true
ignorewsamount = true
ignoreblanklines = true

to ~/.hgrc affects the output of "hg export".
this is wrong because the export output must produce output which is 
definitely acceptable for "hg import" and the above settings break that 
invariant.
