= What is the Problem =

It looks like that *astfits* gets caught in an *infinite loop* when
_printkeynames_ switch is on for the standard _tpv.fits_ file from NASA. It
does print all keynames, however, it doesn't let go of the command prompt and
the CPU usage shoots up to 100%.

= What did I Expect =

Exit after printing all keynames.

= Steps to Reproduce =


$ wget "https://fits.gsfc.nasa.gov/registry/tpvwcs/tpv.fits"; -O tpv.fits
$ astfits tpv.fits -h0 --printkeynames 


= Version = 

Fits (GNU Astronomy Utilities) 0.17.94-b3c7
