variable name error in documentation: scaleat_lat could be scale_at_lat

[kura-okubo]

Dear GMT.jl contributors,

I found an error of variable name in the documentation of coast.

Enviroment

macOS Mojave 10.14.5
gmt 5.4.5

Issue

In the explanation of -L or map_scale:

– mapscale=([map=true, inside=true, norm=true, paper=true,] anchor=refpoint, scaleat_lat=lat, length=len [,align=side, justify=code, fancy=true, label=lab, offset=(dx,dy), units=unit, vertical=true])

scaleat_lat could be scale_at_lat. This causes error when plotting map scale on the figure.

To reproduce that error

using GMT

region = "-5/42/10/52.5r"
proj = (name=:Cassini, center=[2.2 48.5])

# This works
map_scale=(map=true, anchor=[5, 44.5], scale_at_lat=45,  length=200, fancy=true, label="[km]")
p = coast(region=region, proj=proj, map_scale=map_scale, land=:gray, DCW=((country="FR", pen=(0.5,:black))), show=true)

# This causes error
map_scale=(map=true, anchor=[5, 44.5], scaleat_lat=45,  length=200, fancy=true, label="[km]")
p = coast(region=region, proj=proj, map_scale=map_scale, land=:gray, DCW=((country="FR", pen=(0.5,:black))),  show=true)

# error message
> pscoast: Syntax error -L option:  Scale origin modifier +c[<lon>/]/<lat> is required

Expected result

Map scale is shown in the figure:

Current result

It does not work with incorrect variable name.

It would be nice if you could modify the documentation.

@kura-okubo Thank you for this info but I'm puzzled because the the markdown source code correctly says scale_at_lat. See https://github.com/GenericMappingTools/GMT.jl/blob/master/docs/src/coast.md

I believe this now solved (very likely a Julia or Documenter bug)

Thank you for fixing that!
