cosmetic changes

[gf-mse]

I am no expert here, so these are mere suggestions:

1. I propose to capitalize "Position, Company" in accordance with Title Capitalization

• motivation: this is is a table title ( nb: some would disagree )

2. Next, I suggest to add a reference to GitHub standard workflow

• motivation: while an ability to use a source control repository is arguably an inherent qualification for an IT professional, one shall not expect each and every one to use this particular system (Git) in their daily practice ; therefore, a simple HOWTO reference seems appropriate. OTOH, an ability to easily pick such a reference is expected.

3. Finally, there is some minor re-wording of the last sentences. In my opinion, this is the most arguable part -- I was basically trying to soften the sentences according to my understanding.

4. One final thing which is not here -- @nazarov-tech has a good point in 1147 referring to Falsehoods Programmers Believe About Names : in the global world, the names are indeed quite a complex story ( and, for one thing, a person still can have no surname at all ). As for the order of the names ( First Name Last Name, or Last Name, First Name ) -- please don't even get me started 😂

So I would rather re-word the instruction at the end in the following manner:

• give a hint that this is not the one and only possible format for a signature, but merely the recommended way -- may be we shall put there something like Names | About ?
• add a link to the source code to serve as an ultimate reference for the signature file specification.
