Generation of locales: made call to tr more robust and added LOWERCASE macro
When calling 'tr' without quoting braces, bash can make really weird things if there are existing 'single-letter-named' directories eg: thierry@thierry-desktop:~$ echo AAA | tr [A-Z] [a-z] aaa thierry@thierry-desktop:~$ mkdir m thierry@thierry-desktop:~$ echo AAA | tr [A-Z] [a-z] AAA The (quick) analysis is that the callee (tr) argvs then contain 'm' thus the translation does not work Using quotes works around it: thierry@thierry-desktop:~$ echo AAA | tr '[A-Z]' '[a-z]' aaa Signed-off-by: Thierry Bultel <thierry.bultel@wanadoo.fr> Reviewed-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
