Hello all,

Here are some more memory leak patches. 

I send here attached modified files that fix a few memory leaks with the 
regular expressions, as well as during the merge. It contains the 
following files, based on version 1.3.2
string.c: added missing regfree 
file.c  : added missing regfree 
merge.c : added recursuve memory deallocation

The previous patches were not fixing correctly or completely the regfree 
leaks.

These have been working okay on a day to day basis. Does not mean bug free 
though ;-) 
I do not pretend to have fixed all leaks.
