[dev-context] trouble with texmfstart and =

[Aditya Mahajan]

texmfstart does not handle = in --argument propertly. For example

texmfstart --verbose --arguments="a=b" bin:echo

gives

texmfstart version 2.0.3
using 'system' call: echo a
a

Notice that oly echo a is being called. This causes problems when I want 
to call echo "a=b". If I try

texmfstart --verbose --arguments="\"a=b\"" bin:echo

I get

texmfstart version 2.0.3
using 'system' call: echo "a
sh: Syntax error: Unterminated quoted string

execution failed

For some reason, texmfstart is truncating the argument before =. Due to 
this bug the vim module does not work anymore.
