So where does that 25 come from?
We strcpy ".merge_link_XXXXXX" or ".merge_file_XXXXXX" into path[]
and run mkstemp() on it, and these templates are 18 bytes long, so I
am puzzled.
Is 25 "just a small random number that is surely longer than these
templates--did not bother to count how long the templates are"?
That's fine by me; I am just trying to make sure I am not missing
anything that turns these templates into a longer filename.
Thanks.
