SPICE and verilog, in spite of the syntactical differences, to
account for the trick that qflow uses to replace the trailing space
in a verilog backslash-escaped name with a second backslash to get
a SPICE-compatible name that can be easily converted back to its
original verilog name without loss of information. What this means
is that verilog can read SPICE files containing verilog names (which
is illegal SPICE) and verilog files containing hacked-backslash
names (which is illegal verilog). This should be mostly harmless
although the wisdom of it is surely questionable.
