rename E__COUNT to ECOUNT

Browse Source 
Rename the #define E__COUNT to ECOUNT to avoid confusion
with "E_STRING" error symbols.

Improve formatting of help/error, help/errno, and help/strerror.

Update .gitignore.

DESCRIPTION
Whenever an operation or evaluation of function returns an error-value,
the numerical code for that value is stored as "global calc_errno value".
With errno(errnum) numeric argument:
The term "global calc_errno value" is an internal calc state.
This is NOT a calc variable called calc_errno.
errno(errnum) sets "global calc_errno value" to the value
errnum and returns its previous value. Unlike error(errnum)
calling errno(errnum) does NOT increment the global calc
error count (see help errcount).
With errno("E_STRING") string argument:
XXX - fill in - XXX
With errno() no argument:
errno() returns the current value of "global calc_errno
value". Unlike error() calling errno() does NOT increment
the global calc error count (see help errcount).

one may immediately before that sequence set the stored error-number
