[bug-recutils] Confusing error message

I fed this input :


into csv2rec

This (correctly) produced an error.  But the error message is very terse and 
IMO very confusing.

$ ./utils/csv2rec foo.csv
csv2rec: error: not enough headers$

1.  There is no newline after the message, so the prompt appears directly after 
the message, which is ugly.
    Some shells (eg: zsh) don't even produce a prompt until it sees a newline, 
so this will appear under zsh
    to have hung.

2.  'not enough headers' might actually be wrong.  More likely it's a case of 
'too many non-header fields'.

3.  The line number of the offending record is not given.  So it would be 
difficult to track down the 
    problem if the input was large.

I suggest a much more verbose and descriptive error, such as 

csv2rec: file %s line %d: %d header fields were read, but this line contains %d
