題目: [Exim] list tab patch
Hi,

I'm testing Exim 4.00 (enticed by the very useful possibilities
added since 3.x). It's interesting so far - not live yet, but
nearly there.

However, I did notice a small problem with the new "list"
definitions. Take the below as an example:

    domainlist local_domains = @


Exim was fine if that line matches "list<space>", but didn't like
me putting a tab right after "domainlist", claiming:

    2002-02-28 21:47:48 Exim configuration error in line 27:
      main option "domainlist" unknown


That struck me as not quite right!


So I wrote a patch and submit it below for other obsessive tab
formatters to try out. Tested on my (FreeBSD) box from source,
YMMV.

To allow tabs and other whitespace after "...list" I effectively
did:

    # remove build symlinks
    rm build*/readconf.c build*/mytypes.h
    # copy source
    cp src/readconf.c src/mytypes.h build*


then applied the following patch:
