cc-mode: c-backslash-column silently truncated to even tab-width

[Jan Djärv]

Hello.

If I set c-backslash-column to 79, I don't get backslahses at column 79, but 
at column 72.  Cc-mode silently truncates the column to an even tab-width.  I 
could not find any documentation on this behaviour, nor is there any way to 
turn it off, so I can get backslashes at column 79.

This behaviour should be documented, and it should be possible to turn it off 
(i.e. always put backslashes at c-backslash-column regardless of tab-width.
