eq­nar­ray209 – A fix for LaTeX 2.09 eq­nar­ray

The pack­age re­de­fines the eq­nar­ray in de­fault LaTeX, both to re­move the ridicu­lous space around the sec­ond col­umn, and to cor­rect a few other bugs.
That which the pack­age mends, is dealt with in the (re­quired) pack­age ams­math, in the form of sev­eral al­ter­na­tive en­vi­ron­ments. Note that the (LaTeX 2e) eq­nar­ray pack­age seems not to deal with the spac­ing is­sue.
