HEAD branch when he updated the kpathsea sources (sorry for the rude word
but it took me an hour)

ignored. In the $VAR form, the variable name consists of consecutive
letters, digits, and underscores. In the ${VAR} form, the variable
name consists of whatever is between the braces.
In any case, ``expansion'' means calling `getenv'; if the variable is not
set, look in texmf.cnf files for a definition. If not set there, either,
the expansion is the empty string (no error). */
