I completely agree.

How about this change? Any advice on the option name and description
would be appreciated. With this patch, the 5 regressions I was
mentioning in my previous e-mail can be cleared by turning this new
behavior off (there is also one other expected regression in help.exp,
since the output of "help breakpoint" is modified by this patch). Before
sending a patch for these regressions, I prefer to wait for comments
regarding this patch.

* linespec.c (decode_line_1): Skip the function prologue if
funfirstline is set, unless adjust_break_after_prologue is
unset by the user. Changes the behavior of the break command
to skip the function prologue when breaking by line number.

* linespec.c (adjust_break_after_prologue): New static variable.
(_initialize_linespec): New function.
* Makefile.in: Update the dependencies for linespec.c
