The short program name is 'gnulib-tool'; the long program name is APP['name'].
They *should* be used as follows:
* When the diagnostic is related to the command-line options,
the long program name should be used.
Rationale: If there is a problem with the command-line options,
there is a certain probability that the cause is the version
of gnulib-tool. The user may have used an older one, whereas they
intended to use another one. That is, they picked one from the wrong
directory, or a git submodule caused trouble. Omitting the directory
would not helpful for the user's investigation.
* Whereas when the diagnostic is related to files that are being processed,
or to other exceptional situations while processing, the short program
name should be used.
Rationale: In this case, the directory from where gnulib-tool is run
is most likely irrelevant; therefore let the diagnostic focus on what
is relevant.

The use of the long program name here is intentional, as explained above.
