If this is from a Makefile snippet, it says that $f is a make variable,
while $$ turns into a literal $f for the shell that make invokes
(something like:
install-info foo /usr/share/info/dir || \
install-info --entry="* $f (foo): $f" $f /usr/share/info/dir
but I don't have the full context for where $f is being defined for why
it is sometimes expanded in make and others by the shell.

Sadly, I don't know install-info enough to answer that one.
