26fcccba9b fix out of bounds write in radiance 
It was using a fixed 64-byte stack buffer for the RHS of format lines.
Lines can be MAXLINE (2048) chars, so a long line could overflow. If we
use MAXLINE for the small buffer as well, we are guaranteed to not
overflow.

thanks HongxuChen

06a40cc7ee sort-of works 
but can't set meta correctly, try:

	$ vipsheader -a sub-CC00050XX01_ses-7201_T2w.nii.gz

see all fields, but

	$ vips copy sub-CC00050XX01_ses-7201_T2w.nii.gz x.v
	$ vipsheader -a x.v

only see a few, odd

d06c2fee22 use exif_tag_get_name_in_ifd() everywhere 
exif tag names change with the ids they appear in, so you must always
use exif_tag_get_name_in_ifd(), not exif_tag_get_name()
