TRANSFORM = s,x,x,

[Hongyi Zhao]

In the Makefile of Emacs, there is the following code:

# Program name transformation.
TRANSFORM = s,x,x,

But I really can't figure out the effect of this transformation, as
shown in the following example:

$ echo emacs-29.0.50 | sed 's,x,x,'
emacs-29.0.50

As you can see, this transformation does nothing.

Any hints for this problem?
