9ed52ab2fa More arithmetic context improvements, corner cases 
* Handle truncate pages greater than or equal to the number of
scans.

d716cdbe8c Fix the multi-output loop 
Resolves #33.

Fixes the arithmetic comparison in the while loop being
incorrect.

Also, handles the situation in which there are more output
files being specified than scans available, in addition
to the already handled reverse situation.

d7484becbc Quote the device argument. 
Without doing so if the device includes a semicolon the following happens:

    % ./scan -x 'brother4:bus7;dev1'
    Scanning...
    scanadf: open of device brother4:bus7 failed: Invalid argument
    ./scan: line 248: dev1: command not found
    Found no scans.

d33c8caa71 performance: pnmtops to temp file 
For some reason when piping the output of pnmtops directly to ps2pdf,
conversion is very slow (especially for color scans).

When writing to an intermediate temporary file, conversion is fast.

Before:

________________________________________________________
Executed in   19.20 secs   fish           external
  usr time    4.01 secs    0.32 millis    4.01 secs
  sys time   20.63 secs    5.30 millis   20.62 secs

After:

________________________________________________________
Executed in  368.06 millis    fish           external
   usr time  378.06 millis    0.00 millis  378.06 millis
   sys time  100.00 millis    2.79 millis   97.21 millis

An improvement of over 50 times!

This should resolve #19.

f1baab604b Fix tmp directory cleanup with verbose 
Can't set multiple traps on the same signal -- ensure that when the
verbose option is set, the regular cleanup is done in addition to the
lockfile cleanup.
