The function
USER_HOME_EXPAND
expands an initial~
in a filename to the user's home directory. It is used in several places and it seems worth promoting to a documented function.USER_NAME_EXPAND
is left, because we need this function very early during startup, in particular before functions likeError
exist, so we haveUserNameExpand
with nice input checking which callsUSER_NAME_EXPAND
.
