Handle core.symlinks=false case in merge-recursive.

Browse Source 
If the file system does not support symbolic links (core.symlinks=false),
merge-recursive must write the merged symbolic link text into a regular
file.

While we are here, fix a tiny memory leak in the if-branch that writes
real symbolic links.
