$USER vs. $LOGNAME and the EnvironmentVariables wiki page

[Patrice Duroux]

Hi,

1. Using CodeSearch, it is not clear to me when to use one or the other.
2. Would it be nice if the EnvironmentVariables page were linked to a
new page named EnvironmentVariablesList (the same way as DotFiles and
DotFilesList)?

Best,
Patrice
