Unrecognized command-line option '--backend-refresh'

[xavierog]

hitch(8) advertises:

hitch/hitch.man.rst

Line 109 in a922f12

``-R --backend-refresh=SECS``

and so does the hitch binary itself:

hitch/src/configuration.c

Line 1407 in a922f12

fprintf(out, "\t-R --backend-refresh=SECS\n");

but the command-line option actually lacks a dash- between backend and refresh: --backendrefresh=SECS:

hitch/src/configuration.c

Line 51 in a922f12

#define CFG_BACKEND_REFRESH "backendrefresh"

@daghf, I can open a PR for this. Do you prefer a docfix, or do we change the code?
