will show only 'Echoe', but not 'Echom'? I though that «When used
inside a try conditional» refers only to the first section of
`:try...' block, not to `:catch' or `:finally' sections.
This indeed looks wrong.
:echoerr generates an error (which, inside a try block, is handled as an
exception). Depending on where the error happens, it may cause an abort of
whatever it is that it is wrapped in.
In the present case, the "Echoe" exception is not caught, so it will
propagate outside the try block we see here, to be caught by an
outside try block if any, or if there isn't, it may (I suppose)
propagate as an error, causing an abort of some script or function
around this try block.
Vimscripts do not normally terminate on errors, and that is the problem
here; it does, when it shouldn't. There is no mapping to terminate, no
function, no surrounding try/catch block into which to propagate the
error. It should just be ignored and the script continue, just as if you
issued the echoe followed the the echom on the commandline.
