ttree asks to create config file even when "--file=FILE" command line option is specified

[KenNeighbors]

Reproduce bug:

mkdir /tmp/src /tmp/dest
touch /tmp/cfg
ttree --file=/tmp/cfg --src=/tmp/src --dest=/tmp/dest
Do you want me to create a sample '.ttreerc' file for you?
(file: /home/ken/.ttreerc)   [y/n]: n

Expected behavior:

ttree -f /tmp/cfg -s /tmp/src -d /tmp/dst

(no question asked about creating config file)

*Fix bug by adding "--file=." to regex on line 47 in ttree:**
