That was reverted as closed won't fix and they said - users *MUST NOT* have
*ANY* unnecessary spaces in the definitions of math functions, such as prior to
comments!

ε-Τeχ is now assumed as the default engine by all current formats and packages
except Plain Τeχ, and required for future development as it expands all fixed

[There looks to be an opportunity for a gΤeχ that removes all arbitrary
limitations, probably imposed because of SAIL or Pascal limitations in original
implementations.]
