[DATALAD RUNCMD] RF: harmonize 'file name' into 'filename' (bids-stan…

…dard#962)

Text is using both 'file name' and 'filename' pretty much to the equal amount
ATM (see git grep outputs below).  Code uses 'filename', and wikipedia has
https://en.wikipedia.org/wiki/Filename and prefers to use 'filename' in it. So
I decided to harmonize  into  'filename'.
