Their presence breaks automake rules when running
in a separate build directory.
And when regenerated cause unwanted "changed files"
in the repository.
As a consequence visual C compilation will fail.
It will still work with a "make dist" generated tar ball.
We need to upgrade the visual C project files
to invoke bison and flex on windows,
or we have to provide these generated files
in a visual C specific directory. (very annoying of course)
Contrary to older versions gnuplot 5 uses "enhanced text mode" per default.
The strings which we pass to gnuplot don't have "latex" semantics,
thus consistently enforce "noenhanced text mode".
Add a function quote_gnuplot_string() to escape and quote strings
in such a way that they will arrive in gnuplot unmodified.

Using conditional expressions within a .control sequence
left some garbage vectors in the current plot.
For example
> let ix = 0
>
> while ix < 2
> let ix = ix + 1
> end
>
> display
"display" reported a variable named "ix < 2"
which was an internal temporary value in said function `cp_istrue()'
let 2foo = someexpression
was silently accepted, even though 2foo is an illegal identifier.
(first letter is a digit)
This was especially irritating, since
print 2foo
has a legal meaning, 2 femto oO, which is 2e-15
(whatever Unit an oO might be)
Reported by Justin Fisher in

a diode model named "1smb4148" could not be found
because it was dropped in `comment_out_unused_subckt_models()'
as a work around the function
is_a_modelname()
is extended to accept an additional pattern which does match "1smb4148"
