When opened file is not the file from last session this button is
activated. Either open other file or just restart johnny (so no file
would be opened).

If there two johnnies and john already runs then other johnny could
overwrite file with file name but john will not overwrite .rec file so
supportive file does not reflect content of .rec file. I could remove
.rec if user asks to overwrite session file.

Other problem is that if all hashes are cracked and stored session
is not for that file then "start attack" asks about overwriting but
john does not overwrite file because all hashes are cracked and we get
old .rec file. We could restore this session but johnny could not show
results in table because table is filled with values from other file.

I tried different variants. It does not seem to produce problems. The
only minor thing is that I attack 2 field (uid) in pwdump format to
gecos while in original file they are not together.

Gecos is done by one field.

ntlm hashes are not supported.

I plan to make copy of passwd file where hash is in gecos field so
`john --show` shows original hash together with password so I could
put password into table reliably.

BTW I do not need fifo here because I craft file once and then call
`john --show` many times.

Ok. Spaces are in name because I do not specify name for config: qt
calculates it itself from application name. I'll put config into
~/.john/johnny.conf .
