coffread.c and one-line functions cleanup

[Philippe De Muyter]

The following patch prevents breakpoints to point at the opening
	{
line of multi-line functions.

Thu May  6 15:25:32 1999  Philippe De Muyter  <phdm@macqel.be>

	* coffread.c (coff_symtab_read): Call `record_line' with the line
	number of the ".bf" symbol only for one-line functions.
